Fe Containing ZSM-5 Zeolite as Catalyst for Wet Peroxide Oxidation of Orange II

WOS: 000287927800001This study presents the catalytic performances of iron containing ZSM-5 zeolites, prepared by ion exchange or hydrothermal synthesis, in catalytic Fenton-like oxidation of Orange II in aqueous solution. The catalyst, ZSM-5 zeolite with Si/Al ratio of 42 loaded with iron by ion exchange, showed the highest activity. The decolorization of 99.7 percent, degradation of 87.0 percent and COD removal of 81.2 percent were achieved over this catalyst at an initial pH of 3.5. Incorporation of iron into ZSM-5 structure increased its catalytic activity. The hydrothermally prepared FeZSM-5 catalyst was more stable against leaching at low pH value due to the iron being in the framework.TUB?TAK (The Scientific and Technological Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [107M625]; Ege UniversityEge University [2009B?L030, 09MUH056]The authors acknowledge the financial support from TUB?TAK (The Scientific and Technological Council of Turkey) under project number of 107M625.
